Cross-site scripting vulnerability in Citrix NFuse 1.6 and earlier does not quote results from the getLastError method, which allows remote attackers to execute script in other clients via the NFuse_Application parameter to (1) launch.jsp or (2) launch.asp.
Citrix Nfuse 1.51 allows remote attackers to obtain the absolute path of the web root via a malformed request to launch.asp that does not provide the session field.
